BACKGROUND
With the development of technology, the requirements for toolboxes has increased. The traditional plastic toolbox, folded and opened in the middle, has two pieces, which are opened toward opposite directions. Such a toolbox has a single open mode and a small storage capacity. Basically, the diameters of the tools such as drills, screw bits, and sleeves are less than or equal to 10 mm, and the thickness of a standard toolbox is 43 mm. The tool kit is packed in the toolbox, which makes it convenient for carrying tools and reduces the chance of misplacing the parts. However, with the development of technology, more and more types of tools with varied sizes are used. To pack all these tools, the size of the toolbox is increasing, and there are diverse designs, such as multi-layer toolbox and four-folded toolbox. Although these toolboxes can carry many tools or tool accessories, there still exist many drawbacks during practical use, which mainly include:
1. large toolbox size and high mold cost;
2. the incompact interior arrangement, and inefficient use of the space;
3. the multi-layer toolbox and four-folded toolbox with a thin box body have poor durability and inconvenient access to the tools;

When the first base body 19 is flatwise, the limiting clamp 25 is exactly inserted into the limiting hole 24 to clamp the tools with the R-shaped groove. Meanwhile, the limiting block 22 is clamped between a pair of limiting protrusions 16 (when the first base body is about to become flatwise, when there is a 1 mm distance between the limiting blocks and the limiting protrusions before intersection, since the box body is made of the ABS material with a certain elasticity, it takes a bit of force to compress the limiting blocks 22 at two ends of the first base body in the position between the pair of the limiting protrusions). Thereby, the clamp base is locked, and the toolbox can be carried with the tools in a safe and ordered condition. Besides, the horizontal stopper block supports the reinforced rib surface 10 on two sides to further strengthen the box.
The front stopper clamping base 18; the front stopper clamping base 18 is used to pack the tools without the ball groove.
